Original application filed October 23, 1919, Serial No. 332,695. Divided and this application filed Deceni- To all whom it may concern: y y

Be it known that I, MALVIN LIGHTER, a citizen of the United States, residing 1 at New York city, county of New York and State of. New York, have invented, certain new and useful Improvements in Measuring-Sheets for Preparing Printing-Plates, of which the following is a full, clear, and concise description.

My invention relates to measuring sheets to be used upon typewritten matter my purpose being to provide a sheet of transparent material having to some extent the function of a gage, and used as hereinafter described. This sheet of transparent material is provided with indicatingmarks so arranged as to enable the sheet to be laid upon and preferably secured to a sheet of typewritten matter, and there so used as to indicate directly to the operator any dif ferences in the lengths of the several typewritten lines, and to indicate the shortages,

if any, of such typewritten lines as com-.

pared with a standard line of predetermined length.

i a More particularly stated I seek to produce a measuring sheet of the kind just mentioned,

and in which the indicating marks are so spaced apart and otherwise arranged as to enable the operator to read 01f line by line at a glance the precise number of spaces, each of the width of a letter. made by a standard typewriting -machine,;which if added to the respective typewritten lines would render them all of said predetermined or standard length. i v

Iseek o render my measuring sheet suitable for use as an article of, manufacture, andto give it such form and arrangement that its use upon typewritten sheets in the manner here contemplated is accomplished without necessitating the marking -or mutilation of such sheets. p y s This application is a dlVlSlOIl of my pending application filed Oct. 23, a 1919, Serial No. 332,695, for a method of preparin plates for printing. h h h eference is made to theaccompanying drawing forming a partof this specification,

and in which like reference characters indicate like parts throughout. all of the figures.

Figure. 1 is a fragmentary plan view of myimproved measuring sheet.

Fig. 2 is a fragmentary plan view ofa sheet of typewritten matter, upon which the measuring sheet is to be used.

Fig. 5" is a fragmentary plan View showing the measuringsheet as applied to the typewritten sheet appearing in Fig. 2.

Fig. 4 is a fragmentary plan view of a typewritten sheet, made by copying line by line the typewritten matter of the sheet ShOWILlILFlg. 2, but inwhichthe spacing is corrected so as to render the lines of uniform and predetermined length.

A sheet of transparent material, in this particular instance celluloid, is shown at a: and is made of sufiicient size to fully cover a typewritten sheet of the kind upon which the measuring sheet is to be used. A number of score lines I), c are carried by the measuring sheet,the score line I) being spaced a little distance. from the edgeof the sheet .The score line b is separated from the nearest one of the score lines a by a distanceequal to an exact multiple of the width of a letter, and hence it follows that each score line a is spacedfromthe scorev line b by some exact multiple of, such letter.

Between the lines o are numerals 1 to 9 inclusive, repeated at intervals and arranged in. groups d, e', f, g, h, k, as shown in Fig. 1.

The lines I) and c and all of thenumerals in the various groups are preferably rather sharply defined, and the numerals should havesuehform as tobe readily distinguishable from such characters as may be made upon a typewriting machine.

. The score lines and numerals thus carried by the measuring sheet constitute indicating marks upon-which the operator can make his readings.

In Fig. 2 is shown a sheet of paper Z, carryingtypewritten matter m, arranged in the conventional manner well known in this art, the typewritten lines thus varying in length, andthe variations being apparent at the right hand side of the. sheet as shown in this figure.

If, now, the measuring sheet be laid flat upon the sheet of paper shown in Fig. 2, so that thescore line b is brought into exact registry with the beginnings of the respective lines, asshown in Fig; 3, it follows that each letter orcharacter ending a typewritten line is shown in some one of the longitudinal spaces designated by the numerals 1 to 9 inclusiveJ I The operation of my device is as follows: The "paper sheet of typewritten matter, say the sheet? showni'n Fig. 2, is spread out and the measuring sheet is placed upon .it and brought into proper registrv with it,

as just described,'so that the operator, looking through the transparent measuring sheet atthe typewritten lines, can see the endings vof the typewritten lines in the various longitudinalspaces designated by the numerals. Thisdone the operator can determine by casual glancesall differences in the lengthsof the typewritten lines, these differences being read off in units, each unit being the width of a typewritten letter or other typewritten character.

Moreover, in doing this the operator is enabled. at the same time to determine the shortage, if any, of each of the typewritten lines from the predetermined length of a straightline, :namely, the particular score line at "the extreme right. This line is so located, relatively to the score line b, as to delineatethe maximum length of line which can be written upon the typewriting ma chine, when the machine is adjusted for use i upon thesheet shown in Fig. 2.'

Thus the operator can ascertain, line by line of the typewritten matter, just how many spaces .are required to be employed in each line, as it is being copied upon a new sheet at as shown in Fig.4, in order to render all of the typewritten lines of uniform length, as shown at'o in this figure.

In practicethe operator, after bringing the measuring sheet 1nto proper registry Iwith sheet Z as, shown in Fig. 3 and as above described, merely treats the sheet Z, with the measuring sheet upon it, as a piece of copy,

fan'd'upon this piece of copy, the sheet 92, shown in Fig; 4, ismade.

'hasits lines all of the same length, which is the length of a predetermined standard This sheet it thus line.

Thefinished sheet shown in Fig. 4 may be used as an original copy sheet, for the production of a printing plate by the phosaid lines being separated by spaces each of the precise width of a standard typewritten character. 1

2. As an article of manufacture, a member of transparent sheet material provided with a group of indicating lines, some of said indicating lines being spaced apart by distances each of the precise width oi a letter made by a standard typewriting machine, said member of sheet material being further provided with another indicating line separated from said group by a distance approximately equal to the length of a typewritten line, said distance being an exact multiple of the width of said letter.

3. As an article of manufacture, a sheet of transparent material provided with indicating lines disposed parallel with each other, and spaced apart by distances each representing the precise width of a. letter made by a standard typewriting machine, said indicating lines each having a. length extending substantially the full length of the sheet, said sheet being further provided with indicating marks for defining said spaces between said indicating lines.

4:. As an article of manufacture, a sheet of transparent material provided with a number of indicating lines disposed parallel to each other and arranged in a group, said indicating lines each having a length approximating the length of the sheet, said indicating lines being spaced apart by dis tances each of which is an exact multiple of the width of a single letter made by a standard typewriting machine, said group as a whole being spaced from one edge of said sheet by a distance approximating the length of a line of typewritten matter.

5. As an article of manufacture, a sheet made of transparent celluloid and provided with an indicating line disposed adjacent one of its margins, and with a plurality of other indicating lines grouped together and disposed adjacent another one of its margins, said last mentioned indicating line be ing spaced apart by distances each equal to the precise width of a letter made by a standard typewriting machine, said last mentioned indicating lines being spaced from said first mentioned indicating line by a blank space free of lines and having an aggregate width which is an exact multiple of the width of the letter made by a standsaid edge and to each other, said lines each ard typewriting machine. extending a considerable distance in the di- 6. As an article ofmanufacture, a transrection of the length of the sheet, said lines 10 parent member having the form of a sheet bein spaced apart by distanoes each of the 5 and provided with a straight edge, said Widt of aletter made by a typewriting member being further provided with a nummachine.

ber of indicating lines disposed parallel to MALVIN LIGHTER.
